【Player Profile #27】Machida Hiroki|190cm Left-Footed CB Aims for the World Cup After Long Injury Spell at Hoffenheim
A deep dive into Machida Hiroki (28, from Tsukuba, Ibaraki), who is targeting a World Cup return after overcoming a lengthy injury layoff at Hoffenheim. After winning the league title and securing a Champions League berth with Union SG, he stepped up to the Bundesliga in July 2025—only to suffer a torn anterior cruciate ligament in his left knee in the very first match of the season.
Koki Machida, 28 years old. Armed with his 190 cm frame and precise left foot, he secured the Belgian league title (the club's first in 90 years) and a Champions League berth with Union SG, before stepping up to TSG 1899 Hoffenheim in July 2025 — only to suffer a torn anterior cruciate ligament in his left knee in the very first match of the season on August 23. Nevertheless, he rejoined partial team training in April 2026 and has publicly declared his intention to be ready for WC 2026. This article organizes the expectations he carries and the challenges he must overcome, as someone our projected 26-man squad piece described as "the left side of the back three, rapidly developed through his European move."

arrow_forward Getting to Know His Hometown
Tsukuba, Ibaraki Prefecture is known as the "Tsukuba Science City," home to national research institutions such as the Geospatial Information Authority of Japan and the National Institute of Advanced Industrial Science and Technology. With a population of around 250,000, its symbols include Mount Tsukuba rising above the Kanto Plain, and the Tsukuba Express (TX) line that opened in 2005 and connects the city to Akihabara, giving it a face as a bedroom community in the greater Tokyo area.
In terms of football culture, the city is home to Kashima Antlers Tsukuba Junior Youth, a youth development affiliate of Kashima Antlers, where Machida began his career. A town where the logical, structured layout of a research city coexists with the pastoral scenery of the Tsukuba foothills can be seen as the origin of Machida's cool-headed, cerebral defending. His performance on the World Cup stage will become a source of pride for Tsukuba.

local_fire_department 2025/26 Season: What Looked Like an Irreversible Blow in His Bundesliga Debut
In June 2025, Machida signed a permanent contract with Hoffenheim on the back of the league title with Union SG — a long-awaited step up that looked set to confirm his place among the top tier. But in the season opener against Bayer Leverkusen on August 23, he tore the ACL in his left knee in the 40th minute and was forced off, effectively missing the entire season.
On April 22, 2026, multiple media outlets reported that he had rejoined partial team training. Machida himself has publicly stated he intends to be fit for the World Cup, but how much of the roughly nine-month layoff he can overcome without lasting setbacks remains to be seen.
| Season | Club | Competitive Appearances | Highlight |
|---|---|---|---|
| 22–23 | Union SG | 19 | First regular European role of his career |
| 23–24 | Union SG | ~45 | Belgian Cup winner |
| 24–25 | Union SG | ~50 | League title, 34 starts |
| 25–26 | Hoffenheim | 1 | Sidelined through injury |
sports_soccer International Career — Key Starter at Left CB in the Back Three
Machida made his senior debut on September 12, 2023, against Turkey (played the full 90 minutes). He has since accumulated 17 caps and 0 goals.
During the WC 2026 Asian Final Qualifiers, he established himself as a starter alongside Ko Itakura in the CB partnership. He was at the heart of a formidable defensive unit that conceded no goals while scoring 14 in the opening stages, including a 7-0 win over China in Matchday 1. He has been praised as "the ideal solution at left of the back three" in Hajime Moriyasu's system, using his left foot to build play and deliver incisive vertical passes.
Machida was not called up for the 2024 Paris Olympics, as Japan chose not to use any overage players. Our preview piece described him as having "developed rapidly through his European move," but the ordeal that has truly tested that development — his long-term injury at Hoffenheim — has far exceeded anything he experienced during his time at Union SG.
star Koki Machida in a Phrase — "Aerial Fortress on the Left" and "The Ideal Left CB" Combined
Two key phrases are essential to understanding Machida.
| Keyword | How It Shows on the Pitch |
|---|---|
| Aerial Fortress on the Left | Dominant in aerial duels from set pieces thanks to his 190 cm, 84 kg physique / Agility that is rare for a tall CB / The decisive headed goal he scored in a cup final during his Union SG days |
| Ideal Left CB in the Back Three | Left-footed diagonal long balls that serve as the launchpad for buildup play / Cool-headed, reading-based defensive intelligence / Versatility to play left of a back three, left CB, or left SB |
The significance of combining both is clear — he packages the left side's structural, technical, and tactical qualities into a single player. Competing with the emergence of Yuki Itoh and Junnosuke Suzuki, his combination of pace and height, along with the experience gained in earning Champions League qualification with Union SG, makes him a truly irreplaceable asset.
favorite Expectations at WC 2026 — A Key to Japan Breaking Out of Group F
Japan are in Group F alongside the Netherlands, Sweden, and Tunisia. Machida is expected to dominate set pieces and control the left flank as the primary starter at left CB in the back three.
| Opponent | Key Attackers | Machida's Expected Role |
|---|---|---|
| Netherlands | Depay and Havertz-type centre-forwards, 4-3-3 with a high line | Concentrate on set pieces using his 190 cm frame; exploit space behind the Dutch defence with diagonal long balls |
| Sweden | Alexander Isak and Viktor Gyökeres — tall forwards with vertical drive | Machida's physicality makes him the ideal matchup; win aerial battles in set-piece defence |
| Tunisia | African side's trademark pace-based wide attacks | Calmly hold position to close down space; flexibility to perform at left SB if needed |
live_tv Social Media & Media Presence
Machida's approach to communication is well-balanced. His Instagram account @koki.machida_official open_in_new has around 58,000 followers, with a healthy mix of personal content (including the announcement of his marriage in June 2024) and match photos. He also maintains an X account at @koki_machida_ open_in_new and an official website at kokimachida.com open_in_new.
His media persona is characterized by a logical yet measured way of speaking. Even while sidelined through injury, he has posted candid updates on his rehabilitation and his mental state, keeping a close connection with supporters.
info The Challenge He Must Overcome: "Making It to the World Cup After an ACL Tear"
Making it back from an ACL tear in time for the World Cup — that sums up Machida's defining challenge. With roughly nine months since his August 2025 injury, there is even a possibility of him receiving a national team call-up before returning to competitive action with Hoffenheim, which makes the question of how sharp his fitness can be absolutely crucial.
Japan's CB options include Takehiro Tomiyasu, Ko Itakura, Yuki Itoh, Shogo Taniguchi, and Junnosuke Suzuki — players who built on their records while Machida was absent. Having been a regular starter who anchored the qualifying campaign in his Union SG days, his final mission is to demonstrate competitive sharpness by the Kirin Challenge Cup match against Iceland on May 31, and then convince manager Hajime Moriyasu during the pre-tournament training camp that he is ready to be relied upon when it counts.
